Hailed as one of the “most important bands in music since the dawn of the rock and roll era” by former President Bill Clinton, Chicago came in at No. 9, the highest charting American band in Billboard Magazine’s Hot 200 All-Time Top Artists. And Chicago is the first American rock band to chart Top 40 albums in six consecutive decades. Chicago was inducted into the 2016 Rock and Roll Hall of Fame.

This year Chicago is performing its historic album, Chicago II, in its entirety as the first set of the concert. While some artists have performed an entire record as their complete show, for Chicago, this will only be the first set before intermission. Chicago II, like the band’s first release, is a double album, and contains the hits “25 Or 6 To 4,” “Make Me Smile,” “Wake Up Sunshine” and “Colour My World.” Chicago II is being considered for the Grammy Hall Of Fame. The second set will be the “world’s longest encore,” as the band jokingly refers to it, filled with its greatest hits.
